B → V1V2 and B → V l l − Angular Analysis

To detect new physics (NP) in B decays one has to look at various final states as NP may affect different final states differently. The decay of B to one or two vector final state is interesting as one can devise many correlations that are sensitive to NP. In this write up we consider B → V1V2 and B → V l+l − decays. When the final state can be reached by both B and B ̄ decays then mixing effects have to be taken into account leading to additional observables 2 B → V1V2 Angular Distribution The most general Lorentz-covariant amplitude for the decay B(p) → V1(k1, ε1) + V2(k2, ε2) is given by [1, 2] M = a ε∗1 · ε∗2 + b m2B (p · ε∗1)(p · ε∗2) + i c m2
